Slug goes MIT, opens GPU text rendering

This is a small release with outsized impact for rendering nerds: text is one of those plumbing problems that quietly dominates polish, and Slug makes a fast path more accessible.

• –MIT licensing plus public-domain patent dedication removes a lot of the legal friction that usually surrounds graphics tech
• –Because it’s reference shader code, teams still need to do integration work, but they get a proven starting point instead of inventing their own pipeline
• –GPU-side text rendering matters most in engines, editors, and UIs that need scale, sharpness, and low CPU overhead
• –The repo’s credit requirement is worth noting for shipping products, even though the implementation itself is broadly reusable
• –Compared with older text stacks, this is a more modern, shader-native approach that should appeal to developers already living in rendering code
